derivative of-4cos^2(x)

Solution

\frac{d}{d x} (- 4 cos^{2} (x))

Solution

4 sin (2 x)

Solution steps

\frac{d}{d x} (- 4 cos^{2} (x))

Take the constant out:

(a \cdot f)^{'} = a \cdot f^{'}

= - 4 \frac{d}{d x} (cos^{2} (x))

Apply the chain rule:

2 cos (x) \frac{d}{d x} (cos (x))

= 2 cos (x) \frac{d}{d x} (cos (x))

\frac{d}{d x} (cos (x)) = - sin (x)

= - 4 \cdot 2 cos (x) (- sin (x))

Simplify

- 4 \cdot 2 cos (x) (- sin (x)) : 4 sin (2 x)

= 4 sin (2 x)
